TITLE

Debian Security Advisory 4736-1

DESCRIPTION

Inappropriate implementation in WebRTC in Google Chrome prior to 84.0.4147.89 allowed an attacker in a privileged network position to potentially exploit heap corruption via a crafted SCTP stream. WebRTC is one of the components that supports browsers for real-time voice or video conversations. A security vulnerability exists in WebRTC in versions prior to Google Chrome 84.0.4147.89. An attacker could exploit this vulnerability to bypass security restrictions. For the stable distribution (buster), these problems have been fixed in version 68.11.0esr-1~deb10u1. We recommend that you upgrade your firefox-esr packages. For the detailed security status of firefox-esr please refer to its security tracker page at: https://security-tracker.debian.org/tracker/firefox-esr Further information about Debian Security Advisories, how to apply these updates to your system and frequently asked questions can be found at: https://www.debian.org/security/ Mailing list: debian-security-announce@lists.debian.org -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEEtuYvPRKsOElcDakFEMKTtsN8TjYFAl8huUkACgkQEMKTtsN8 TjZrWRAAmJKPn+TnXVDcxt9OC/ko2aovs7IotOScCOvjO9Aez+l64cUEOAj4Zxc1 gd/CC/fW/LNudbmLrMKjGft3bFwi/78htATpgcJE5diEjEVlyvgMJiwvwoN+zOO2 1u4hgN6sYiBVnEKBOtS3wA0VGa19tW5mWXWZgtfmEMfuNpz3bUQ8ApQ48M47VdUO JjZbtTP92N8h99Mko3k2Z2xUDimRZ0xvVYXmEQ9lUzQnNpz0yKwSuo/GsjnH3l1n 2Y8ih+m9pCuYfcpXvWtLlQc70koS84MaAzdqYsp1xMpXLHzejDM/e0oDEJppBjwP 0U4qHSbirlwMHn1PSILFsDjYfTwSmFUqvmPb9mcPMnz60xuh6IT+2RUKXekBo263 1uhlHgqd5+hWYuWxQz7FgssJVUzfH2ZzaIoTRTYtTQVJmHeYViWf54AEGP36D6++ I8tNyCVTbDW+114dWjAmkuQ+yVjt0eSb4rqLqwcKxvNT6cCzRRJp2/tSsQCAvFdB dzExvQQMD/t4o+0BUYxani0jJf9DR9N7BoUBQdI0eZNV/mJ1BmDWXJqEpExhilfb 9QlI6oRu/Cw05BpkD1FKeXR+MgMKpi/jubhsYkZQcV9t7C0D/L13DEAqxr4zi4te eLLP/BQ3bl+h71ZHBCYCpbCc+joreguC3Z09IaDYFafewmOACHs= =QMwo -----END PGP SIGNATURE----- . WebRTC: usrsctp is called with pointer as network address When usrsctp is used with a custom transport, an address must be provided to usrsctp_conninput be used as the source and destination address of the incoming packet. WebRTC uses the address of the SctpTransport instance for this value. Unfortunately, this value is often transmitted to the peer, for example to validate signing of the cookie. This could allow an attacker access to the location in memory of the SctpTransport of a peer, bypassing ASLR. To reproduce, place the following code on line 9529 of sctp_output.c. This will output the peer's address to the log: struct sctp_state_cookie cookie2; struct sctp_state_cookie* cookie3; cookie3 = sctp_get_next_param(cookie, 4, &cookie2, sizeof(struct sctp_state_cookie)); LOGE(\"COOKIE INITACK ADDRESS %llx laddress %llx\", *((long long*)cookie3->address), *((long long*)cookie3->address)); Or, view the SCTP packets sent by WebRTC before they are sent to the encryption layer. They are full of pointers. This bug is subject to a 90 day disclosure deadline. After 90 days elapse, the bug report will become visible to the public. The scheduled disclosure date is 2020-Jul-28. Disclosure at an earlier date is possible if agreed upon by all parties. Related CVE Numbers: CVE-2020-6514.
